I think this picture was from the wine party in january. DR posted also about it. In his post his sweater is the same and you see a bit of Heidi. De window behind is also the same.

But probably they are somewhere together. Could be anywhere....
Edit: DR and HB always post things with delay. Probably the wineparty and al pictures for the dr3wines campaign were made around 20 january. Here is a picture with a fan at the winery, same sweater as the other pictures
